A distributed parameters model for solar cells

Abstract

The distributive circuit element model consists of a chain of T elements. The elemental model is made up of series and shunt paths. The sheet resistance of the diffused layer constitutes the series path. The shunt paths are three-fold, consisting of the diode together with a series resistance, a conductance and a light generated current source. For a given cell, the parameters used in the model can be obtained by measuring the potential profiles for reverse-biased, forward-biased and short-circuited illuminated conditions and feeding the data obtained from the measurements in the solution of the differential equations for the model. The model has been successfully employed to compute optimum gridding for the cell.
